Comment 1 Søren Sandmann Pedersen 2010-04-17 11:13:43 UTC 
Thanks for the bug report. Can you try running under valgrind and attach the logs?

I can't reproduce here, though my versions of evince and poppler are somewhat old.
Comment 2 Søren Sandmann Pedersen 2010-04-17 11:15:09 UTC 
Also, does this happen with pixman 0.18.0 too?
Comment 3 Søren Sandmann Pedersen 2010-04-22 05:17:01 UTC 
This is another case of cairo creating a (0, 0) image and trying to composite with it. 

We usually consider these cairo bugs, but maybe pixman should just filter them out.
Comment 4 Cyril Brulebois 2010-04-23 05:36:59 UTC 
For the record: Yes it still happens with pixman 0.18.0.
Comment 5 Chris Wilson 2010-05-13 02:10:29 UTC 
This is fixed in 1.10, the changes are too violent to be backported to 1.8.
Comment 6 Chris Wilson 2012-04-10 16:07:24 UTC 
Concluding as a cairo bug, fixed in 1.10.
